Seed won't be ready for several weeks after the flower fades. Wait until it is dried out and black - both the seed head and the stem near it. Separate the seed out and make sure it is bone dry. Many native plants, Rudbeckia included, need a cold, moist period before seed will break dormancy. To achieve this, there are 2 options. Option 1 is to sow seed in late fall where you want it to grow. The other option is to save the seed, mix it with a small amount of slightly dampened sand, sterile potting mix or vermiculite and store in the refrigerator in a plastic bag. Start the seed indoors 4-6 wks before your frost free date. I don't know which type of Rudbeckia you have (Rudbeckia triloba?) but many only form basal leaves the first year. Expect blooms in year two and thereafter. The seeds need light to germinate so don't cover them with soil.
